they in essence already are truly dynamic in tip/master. Not yet

easier to test and validate than to keep a farm of cross compilers to 
other arches alive.)

But by all means SPARSEIRQ is the primary and only model on x86.

We could even plug in the dynamic vector allocator from Alan Mayer now, 
both on 32-bit and on 64-bit x86: Yinghai, any complications expected 
there? I guess we need to unify the local APIC code first.
